From d6b33439281d1b8cf93b0c5c5ecabcd9c6e7baad Mon Sep 17 00:00:00 2001
From: "Luke D. Jones" <luke@ljones.dev>
Date: Sat, 2 Dec 2023 17:47:59 +1300
Subject: [PATCH v14.7 2/4] HID: asus: make asus_kbd_init() generic, remove
 rog_nkey_led_init()

Some of the n-key stuff is old and outdated, so
make asus_kbd_init() generic to use with other
report ID and remove rog_nkey_led_init().
